Three days late

Taken four tests. All came back negative. I’m not sure if the tests are good? I bought a bulk of 20 tests off amazon. ClinicalGuard, brand. I’m usually never late. And when my period comes I have sore breasts and cramping a week before. I have no symptoms at all. I feel normal. This is the test today. I’m really hoping I get a positive soon! I was thinking of going to get a first response test. But I’m trying to wait it out till my period is a week late. Anyone been late and kept getting negatives, but ended up pregnant anyways?
